ithink so

Answer:

As

[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{2}{5}[/tex]

Therefore,  option C is true.

Step-by-step explanation:

Given the expression

[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}[/tex]

as

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]

so the expression becomes

[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{4^{\frac{1}{2}}}{25^{\frac{1}{2}}}[/tex]

          [tex]=\frac{4^{\frac{1}{2}}}{25^{\frac{1}{2}}}[/tex]

          [tex]=\frac{2}{25^{\frac{1}{2}}}[/tex]

            [tex]=\frac{2}{5}[/tex]

Hence,

[tex]\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{2}{5}[/tex]

Therefore,  option C is true.

Answer:

B

Step-by-step explanation:

this is the correct awnser because the thingy is y-y¹=slope(x-x¹) so for y¹ it would be 2 and that gives away the awnser. because all of the other ones have different numbers if the minus sign is an addition sign it mean that the y¹ is negative which it isnt.

how you would find the y¹ is you look on the y-axis and see where the line goes through perfectly which is the positive 2

Answer:

The equation that represents the amount that Aziz earns for the number of lawn he mows is e = 15.875 × n

Step-by-step explanation:

From the graph, we have;

For the point where n = 4, we have e ≈ 63.5

Therefore, we have;

The slope = Δn/Δe = 63.5/(4) = 15.875

The coordinates of the points plotted on the graph are as follows;

n = 0, e = 0, therefore, the y-intercept is 0, and y = slope × x

n = 1, e = 1 × 0.79375 = 15.875

n = 2, e = 2 × 15.875 = 31.75

n = 3, e = 2 × 15.875 = 47.625

n = 4, e = 4 × 15.875 = 63.5

We have, e = 15.875 × n

Where, n represents the number of lawns Aziz mows, and n represents the amount of earnings Aziz makes in dollars

Therefore, the equation that represents the amount that Aziz earns for the number of lawn he mows is e = 15.875 × n

If there are 25% discount on the pair of shoes, then the sale price of boots are, $71.24

Sale price refers to the price at which a product or service is offered for sale after a discount or reduction from its original or regular price. Sale price is a promotional tool used by retailers to encourage customers to purchase products or services by offering them at a lower price than their regular price. The purpose of a sale price is to increase sales and generate revenue, as well as to clear inventory, attract new customers, and increase brand awareness. The calculation of sale price is typically performed by subtracting a certain percentage or dollar amount from the original or regular price.

Given that,

The boots are $94.99 and are 25% off,

so the discount amount is

⇒ $94.99 x 0.25 = $23.75.

The sale price of the boots is

⇒ $94.99 - $23.75

⇒ $71.24

Rounded to the nearest cent, the sale price is $71.24

The perimeter of the smaller polygon from the given ratio is 100 centimeters.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, the scale factor of two similar polygons is 2:3.

The perimeter of the larger polygon is 150 centimeters.

Let x be the perimeter of the smaller polygon.

Now, 2/3 =x/150

⇒ x=100 centimeters

Therefore, the perimeter of the smaller polygon is 100 centimeters.

Answer:

[tex]x^2 + 15x - 60 = 0[/tex]

The actual dimension is 18.28 by 3.28

Step-by-step explanation:

Given

Dimension:

[tex](x + 15)\ by\ x[/tex]

[tex]Area = 60in^2[/tex]

Required

Determine the quadratic equation and get the possible values of x

Solving (a): Quadratic Equation.

The cardboard is rectangular in shape.

Hence, Area is calculated as thus:

[tex]Area = Length * Width[/tex]

[tex]60= (x + 15) * x[/tex]

Open Bracket

[tex]60= x^2 + 15x[/tex]

Subtract 60 from both sides

[tex]x^2 + 15x - 60 = 0[/tex]

Hence, the above represents the quadratic equation

Solving (b): The actual dimension

First, we need to solve for x

This can be solved using quadratic formula:

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 1[/tex]

[tex]b = 15[/tex]

[tex]c = -60[/tex]

So:

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]x = \frac{-15 \± \sqrt{15^2 - 4*1*-60}}{2*1}[/tex]

[tex]x = \frac{-15 \± \sqrt{225 + 240}}{2}[/tex]

[tex]x = \frac{-15 \± \sqrt{465}}{2}[/tex]

[tex]x = \frac{-15 \± \21.56}{2}[/tex]

Split:

[tex]x = \frac{-15 + 21.56}{2}[/tex] or [tex]x = \frac{-15 - 21.56}{2}[/tex]

[tex]x = \frac{6.56}{2}[/tex] or [tex]x = \frac{-36.36}{2}[/tex]

[tex]x = 3.28[/tex] or [tex]x = -18.18[/tex]

But length can't be negative;

So:

[tex]x = 3.28[/tex]

The actual dimensions: [tex](x + 15)\ by\ x[/tex] is

[tex]Length =3.28 +15[/tex]

[tex]Length =18.28[/tex]

[tex]Width = x[/tex]

[tex]Width =3.28[/tex]

The actual dimension is 18.28 by 3.28

Answer:

40 gallons

Step-by-step explanation:

Let the number of gallons that would completely fill the bathtub be represented by N.

Since 12 gallons of water gives 30% of the number of gallons to fill the bathtub, then;

30% of N = 12

[tex]\frac{30}{100}[/tex] x N = 12

30N = 12 x 100

30N = 1200

divide both sides by 30,

N = [tex]\frac{1200}{30}[/tex]

   = 40

The number of gallons that would completely fill the bathtub is 40 gallons.

Answer:

-2 < y ≤ 10

Step-by-step explanation:

The graph's lowest point is at y = -2, and the graph's highest point is at y = 10, so we know it would start off with -2 and end with 10. The dot at the lowest point is not shaded in, indicating that the graph does not include -2. So, we would represent this exclusion in our inequality with a less than (<) sign. As for the highest point at y = 10, it is shaded in, indicating that the graph does include 10. We would show this in our inequality with a less than or equal to sign (≤)

Answer:

The horizontal distance between the lifeguard and the person is approximately 24.751 feet.

Step-by-step explanation:

At first we include a geometrical representation of the statement, which is shown in the image attached below. We can determine the horizontal distance between the lifeguard and the person by means of the following trigonometrical relationship:

[tex]\tan \theta = \frac{OL}{OP}[/tex] (1)

Where:

[tex]\theta[/tex] - Angle of depression to the person, measured in sexagesimal degrees.

[tex]OL[/tex] - Height of the lifeguard above the ground, measured in feet.

[tex]OP[/tex] - Horizontal distance between the lifeguard and the person, measured in feet.

If we know that [tex]OL = 10\,ft[/tex] and [tex]\theta = 22^{\circ}[/tex], then the horizontal distance between the lifeguard and the person is:

[tex]OP = \frac{OL}{\tan \theta}[/tex]

[tex]OP = \frac{10\,ft}{\tan 22^{\circ}}[/tex]

[tex]OP \approx 24.751\,ft[/tex]

The horizontal distance between the lifeguard and the person is approximately 24.751 feet.

Answer:

7/15

Step-by-step explanation:

find a common demonator for example 15

you would do 4x3 for 12 and 5x3 for 15 so your first fraction would be 12/15

for the second fraction you will do 1x5 and 3x5 so your fraction would be 5/15

then you just subtract.

Answer:

7/15

Step-by-step explanation:

4/5 - 1/3. Change the denominators to 15, do they same to the numerators which is multiply by 5. You then have 12 minus 5 = 7. So 7/15.

Answer:

3.5 pounds of the mixture was almonds

Step-by-step explanation:

Assume that the mixture contains x pounds of cashews and y pounds of almonds

∵ x represents the amount of cashew

∵ y represents the amount of almond

∵ Eduardo mixed 5 pounds of cashews and almonds

∴ x + y = 5 ⇒ (1)

∵ Cashews cost $8 per pound

∵ Almonds cost $6 per pound

∵ The total cost of the mixture was $33

→ Multiply x by 8 and y by 6 and equate their sum by 33

∴ 8x + 6y = 33 ⇒ (2)

Now we have a system of equations to solve it

→ Multiply equation (1) by -8 to eliminate x

∵ -8(x) + -8(y) = -8(5)

∴ -8x - 8y = -40 ⇒ (3)

→ Add equations(2) and (3)

∵ (8x + -8x) + (6y + -8y) = (33 + -40)

∴ -2y = -7

→ Divide both sides by -2

∴ y = 3.5

∵ y represents the amount of almond

∴ 3.5 pounds of the mixture was almonds
